Connectors

3. Connectors

3.1. Antenna

The cable for connecting the antenna is fitted with an FME type
connector. Use a connector of the corresponding type and impedance as
its mate.

Important

CAUTION. The router cannot be connected to the power supply
without the antenna connected (or corresponding artificial load).
Otherwise this could lead to damage to the radio part of the
router.

3.2. Serial Interface

The router can be equipped with serial ports RS232 or RS422/485, the
ports can be optical isolated. According to the configuration it is possible
to use a terminal block or DSUB 9 (Canon) connectors for connecting data
cables via the serial interface. See Chapter Dimensional Diagram
and Labeling. Data rate on the serial interface can be from 200
bps to 230,400 bps.

c) Connection diagram of data cable RS485

When you are connecting RS485, your “A” has to be
connected to TxD+ and RxD+ simultaneously and “B” to TxD- and
RxD- simultaneosly.

Important – For making data cables
for connecting the user´s terminal equipment to the serial port we
recommend using a shielded cable, particularly in an industrial
environment, and connecting the shielding to GND (pin No. 5). When using a
multi-core cable all free conductors should be connected to pin No. 5. In
the case of a galvanically separate port for RS485 (RS422) only ground one
side of the data cable. We recommend using only the necessary minimum
length for data cables.

3.2.2. Distinguishing Data Modules by Colour

For RS232 RxD is the output from the router (approx. -6V when
inactive) and TxD is the input to the router (according to the RS 232
standard). Hardware versions of the interface can be distinguished
according to the colours of LED diodes next to the connector.

Tab. 3.3: Table for distinguishing LEDs for RxD and TxD by colour

Type of interface

Colour (RxD / TxD)

RS232 opt. separated

orange / green

RS422/485 opt. separated

orange / yellow

3.2.3. Labelling of SCC terminals

Fig. 3.4: Labelling of serial interface terminals

The SCC ports of the router are DCE type devices. Based on standards
the receiver terminal RxD of the connected DTE device is connected to the
transmitting terminal of the router’s SCC port which is also labelled RxD.
Similarly the red LED indicating transmission from SCC is labelled
RxD.

The direct cable serves for connecting to the Ethernet network via
the hub (repeater) or switch-hub (router).

A crossed cable serves for connecting only two devices –
MR400-MC100, MR400-PC, etc.

The ETH module consumption is 30 mA (60 mA until 07/2008).

The following table contains connector connections and colours of
conductors. For the crossed cable the order of conductors on one side is the
same as for the direct cable.

3.4. Analog and Digital Inputs and Outputs

The module of analog and digital inputs and outputs (ADIO) is designed
for :

creating 20 mA current loops

switching loads supplied with DC and AC current

scanning digital signals

Each functional group of terminals is galvanically separated from the
rest of the device as shown on the internal layout diagram for the ADIO
module on the image below:

Fig. 3.6: Wiring diagrams for analog and digital inputs and outputs

3.4.1. Labelling

Individual terminals of terminal blocks are labelled:

Connector A OUT

– analog outputs

Connector A IN

– analog inputs

Connector D OUT

– digital outputs

Connector D IN

– digital inputs

Terminal UP

supplying load max. 30 V DC, 24 V AC–

The MORSE router used in the
diagram showing examples of wiring can, of course, be replaced
by any MORSE system equipment (e.g. MD160, MX 160, MWxxx, MRxxx,
MC100, MG100i, …)

3.5. Supply Connector

Terminals of this connector are labelled in the standard manner.
Only DC voltage in the range from 10.8 to 15.6 V can be connected.
Connecting higher voltage may damage the router.

Terminal PI (power indicator) – if the router is fed from the
MS2000 power supply information about supply method from source clamp
MAIN PWR OFF can be lead:

3.7. Service Connector

The service connector RJ-12 serves for short-term connections of the
service cable during local adjustment of MORSE router parameters. Upon
attaching the connector (connecting to the RS232 link (RxD,TxD, GND)) the
router automatically switches to service mode and the module slot 1
disconnects. Slots numbering see section Section 3.9, “View of MG100 router”.

3.8. Inserting SIM cards into the reader

There is an opening at the bottom edge of the right side of the
router through which the SIM card holder is inserted into the plug-in
reader.

The SIM card holder is released by pressing the yellow ejector
button inside the opening next to the SIM card holder using a suitable
sharp tip, e.g. a ballpoint pen.
